SEWINGJVIACHINE LOOP-TAKER.

Application filed November 27, 1911.

To all whom it may concern lie it known that We, PHILIP DIEHL and MARTINHnMLnn, citizens of the United States, residing at Elizabeth, in thecounty of Union and State of New Jersey, have mvented certain new anduseful Improvements in Sewing-Machine Loop-Takers, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

In Patent No. 663,808, of December 11., 1900, is described a revolvinghook sewing machine without a bobbin-case ring having an early cast-offand in which the bobbincase contains an L-shapcd flange having a bearingWithin a correspondingly formed gain of which the approximatelydisk-like shank of the hook forms the inwardly pro 'jecting member.

One feature of our invention consists of a hook gain of less diameter.than the hook shank. i

Another feature consists in the reforming of the hook shank into anapproximate cylinder outside the hook gain.

Another feature of our invention consists of a gain cover independent ofthe hook shank.

.Another feature of our invention consists of separating the hook throat(whereby the loop is deflected into the loop-retainer) from the hook andmounting the same in a part in alinement with said gain.

Another feature of our invention consists in dispensing with thehook-shank surface wherein the outer branch of the -thread rolled overthe gain in said Patent No.

(363,808, and in cxteri'orly confining said outer branch to theapproximately cylindrical hook near the point at which said gaincommences.

Another feature of our invention consists Specification of LettersPatent.

' in making the gainor raceway-cover elastic to enable it to yield toprevent the clogging of the raceway.

Another feature of our invention consists in forming in both the hookmember and bobbin-case ring clearing slits transverse to the raceway,and the tongue fitted thereto.

riphery of the case.

Certainpther features of the present invention will be set forth in thefollowing description and recited in the appended claims.

In the following description and the appended claims, we employ the wordforward to indicate the direction longitudi nally of the axis of motiontoward which the hook faces, and the word advance to indicateapproximately circumferentially in the direction toward which the hookadvances in seizing the neelle-thread loops. Each of these terms denotesa direction relatively to the axis of rotation or oscillation. whetherthat axis be horizontal or vertical or inclined.

Fig. 2 is a. front view and Fig. 3 a rearview of a loop-taker containing the present improvements. Fig. 4- is aperspective view of the hook member. Fig. 5 a face view of the same,Fig. (i a transverse section thereof and Fig. 7 a face view similar toFig. 5, but with the racewaycover in position. F 8 is a perspective viewof the raceway-cover. Fig. 9 is a perspective view of the bobbin-csering or holder taken from the rearward side. Fig. '10 is a plan of thebobbin-case, Fig. 11 a perspective view of the same, Fig. 12 a verticalsection thereof and Fig. 13 a perspective view of a detail thereof.

ihe loop-taker of the present improve- ..rent is represented ascr'nnprising a hookniembcr or ring, a bobbin-case section or.

holding ring journalcd therein, and a hobb1n-case section in the form ofa cap removably sustained by said holding ring, but it is evident thatcertain features of the pres mental body connected at the inner edge bya series offdished radial arms 2 with the hub 3 centrallyapertured toadmit the forward endof' the hook-shaft upon which it is adapted to-.be' secured.

The'hook-ning has upon the .outer edge of its forward face a forwardlyextending segmental flange a whose advance portion forms the sl'zink'fof the-'loop seizing hook or beak .fi -projecting in advance,thereof beyond the adjacent.fextremity of the hook-ring 1 and at' anangle with theperipherythereof and having its pointfi substantially inline with ,the extreme cuterforforward edge of the flange 4 and itslower edge 6" inclined backward-1y and merging into the inner edge ofthe hook-ring-to afford a loop-deflecting surface. The .bea'k' of' thehook-member is, in a radial direction, of .an approximatelyuniformthinness from point to base. It is of the beak 5 with its,outeredge 8 inclined backwardly and longitudinally of the axis of movement ofthe beak, as represented in' Fig. 6, to afford a loop-deflecting surfaceand forming at its unction with the latter a throat 9 substantiallyparallel with the axis of. the hook-ring and having its forwardextremity at the forward edge of the hookshank. The opposite end portion4* of the flange 4 has a forwardly inclined edge to afforda lower threadpull-off for drawing suflicient thread from the bobbin for theproduction of each stitch.

,The hook-ring 1 has in its forward or outer face a forwardly facingcircular bearing groove or raceway 10 which is of less diameter than thehook-shank, as represented particularly in Fig. 5, and the inner wall ofthis groove is cut down to a smaller depth than the outer wall.

The bobbin-case holder or carrier is constructed with the annular body11 formed exteriorly with an L-shaped peripheral tongue comprising theannular rib 12 adapted to rest upon the seat afforded by the margin 10*of the hook-ring groove 10 and an inwardly extending member formed as anannular lip 13. entering and fitted to the opposite walls of the groove10. The L-shaped tongue thus produced is cut away on one side to formthe loop-detaining hooked shoulder 14, tapered toward the outer face ofthe tongue, and the heel or loop-confining shoulder 15. The interruptionof the hookring is greater than that of said tongue on the bobbin-caseholder for reasons which will presently appear.

Secured upon the outer or forward face of the hook-ring by means ofscrews 16 tapped into threaded apertures 17 therein, beyond the-rearwardend ofthe flange 4 and near the extremity farthest from the beak 5, isthe fiat segmental cover-plate 18 whose inner margin overhangs thegroove 10 and forms therewith an L-shaped raceway open upon the sidetoward the axis of the hook-ring to receive the L-shaped tongue of thebobbin-case holder. As represented particularly in Figs. 5 and 6, theL-shaped groove (Jr-raceway of the hook has an annular portionor memberwith spaced integral side-walls concentric with the cylindrical body ofthe hook, the outer side-wall being the full depth of the racewaybetween the bottom of such groove and the adjacent face of thecover-plate 18, and an inwardlyv extending portion or member inangular-1c lation therewith and spaced from the adjacent face of saidcover-plate. -The coverplate 18 is preferably made of resilient materialand sufiiciently thin to enable its free extremity to yield outwardlywithin a lateral groove or pocket .19 adjacent the base of the beak inwhich suitable clearance is provided for the purpose, the extremity ofthe cover-plate resting lightly upon the outer face of said tongue tohold it yieldingly seated within the raceway of the hookring. Thefreeextrcmity of the racewaycover is formed in the marginal portionoverhanging the bearing tongue with a thread-engaging element or a nose18 whose inner edge affords a convex loop-deflecting surface which isshown flanking on the inside the base of the beak 5 which is flankedupon the outer side by the loop-spreading member 7. It will be observedthat the operative portions of both the loop-deflecting nose 18 and theloop-spreading mraaber 7 are disposed backward of the point' of thehook'both circlunferentiallyand axially. The object of theloop-deflecting surface of the nose 18 is to thrust aside the inner limbof a needle-thread loop carried past loopseizing position bynthe beak ofthe hook so as to-be caught by the loop-detaining shoulder 14 of thebobbin-case holder while the outer limb is carried over the outer faceof the bobbin-case by the continued movement of the hook-member.

As represented in the drawings, the hookring is provided with clearingslits 20 disposed transversely toand in intersecting re lation with thebearing groove 10, and the bearing ton ue of the bobbin-case holdingring is simi arly provided with a series of transverse clearing slits21. In case, owing to the general character or defects in the jneedle-thread, the inner limb of the loop tongue 25 85,

l restraining porting post 23 but to be should at times fail to becaught by the detaining shoulder 14 and be introduced within theraceway, theparts would be prevent ed from jamming by the yielding ofthe free end of the raceway-cover, and the two series of clearing slits20 and 21 would produce a shearing action upon the interposed threadWhile affording desired apertures to enable the particles of thread tobe ejected so as .to effectively maintain the raceway cleared.

he same is true of any particles of lint or dirt which might beintroduced in the raceway. By this means, the free running of theoperative parts of themachine is insured.

The thread-case body-section or holding ring 11 is provided at its innerend with the cross-bar 22 sustaining the axially disposed pin or post 23provided with an annular-1y notched head 24 of Wellknown form. It isshown provided with a forwardly extending having a tapered and outwardlybent extension 26 formed with the parallel sidednotch 27 to admit adetaining lug for the holder against rotation with the hook member, allas described more fully in our pending application Serial N 0. 638,059,filed July 12, 1911.

'The thread-case is shown formed with a cylindrical. body '23, open atits inner end and formed with a closed outer end whichcarries an axialtubular post 29 whichis in practice fitted upon the supporting pin 23 4of the holding ri g 11 as a bearing,

and upon which is mounte the bobbin 30 carrying the mass of lower threadZ). In general constructive features, this case is similar to that ofour pending application Serial No. 626,734, filed May 12, 1911, thefront end of the bobbin-case being provided withundercut guide-ribs 31to which are fitted the op posite edges of the spring-pressed latchplate32 formed with an aperture 33 adapted to engage the necked head 24 ofthe supdisengaged by shifting the apertured lever-plate 34 for removalof the thread-case. The peripheral wall of the thread-case is providedwith an inclined threading slit 35 extending from the open inner end toan'aperture 36 inter.- mediate its ends. v

As represented in the drawings, the closed end of the thread-case isformed with a needle in its loop-presenting position, and at one side ofsuch cut nearest the threading slit a thread guiding tongue 38 isproduced by a slit extending from the edge to the clearance cut 37adjacent the rib 31 and another cut which disconnects the edge of thetongue from the cylindrical wall of the case, a thread-delivery aperture39 being thus formed between the tongue and the adjacent edge of theside wall of the case. The aperture 39 is substantially closed at theend adjacent the clearance cut 37 by means of the inturned i lip 10 of aspringplate 41 riveted or otherwise secured upon the tongue 33.

Secured uponthe periphery of the threadcase by means ofscrews t2 and 43is the ten sion spring 44; whose operative portion overlies the spacebetween the terminal aperture 36 of the threading slit andthe outer edgeof the case adjacent the base of the tongue 38. The pressure of thespring upon the exterior of the thread-case may be adjusted by the usualmanipulation of the screw 4C3. In applying a bobbin, the latter isintroduced in the open end of the thread-case and the thread drawnthrough the threading slit 35, beneath the the outer end of theguide-tongue 38 and thence intermediate the confining lip and the edgeof the side wall into the aperture 39 from which the correct lead of thethread to the under face of the work is insured in the operation of theloop-taker, the threadcase being locked against turning relatively tothe stationary holding member 11 by engagement of its shoulders 45 and46 with the edges of the tongue 25 of the holding member. 1

Referring now more particularly to Fig. l, the frame comprises thebed-plate 47 with overhanging bracket-arm 48' in which is journaled themainorneedle-driving shaft 9 carrying-at its rearward end the drivingpulley 50 and adjacent the, same, within the hollow standard of thebracket-arm, the pin pulley 51 embraced by the flexible perforated belt52 which is shown crossed and encir- -clingthe smaller pin-pulley 53fixed upon the rearward end of the loop-taker shaft 54 journaled beneaththe bed-plate of the ma chine and receiving two rotations for eachrotation of the main-shaft. The hub 3 of the hook-ring is fixed upon theforward end of the shaft 54 in the usual manner, and the thread-case isheld stationary within the hook by means of the arm 55 secured to atension spring 4%, under stationary part of the machine and formed witha lateral lug 56 entering the notch 27 of the bobbin-case holder.

Cooperating with the loop-seizing member in the production of stitchesis the eye-pointed needle 57 carried by the reciprocating needle-bar 58journaled in the head of the bracket-arm and having fixed thereon thecollar 59 carrying the lateral stud 60 which is embraced by a boss atone end of the pitman 61 whose opposite end embraces the crank-pin 62 ofa block 63 at the outer end of the take-up crank-pints which is fixed inthe crank-plate 65 secured upon th'forward end of the main-shaft 49.

The crank-pin 64 is embraced by the lower end of the link 66 connectedby means of the pivotal pin 67 with the free end of the swinging arm 68whose other end has a boss fitted upon the stationary fulcrum-pin (i9fixed in the head of the bracket-arm. The link 66 is provided at itsupper end with the outwardly extending take-up arm 70 having thethread-eye 71 which is thus offset from the pivotal connections of saidlink with the actuating crank-pin and the arm 68.

The feeding mechanism is shown comprising the feed-dog 72 which inpractice works through the usual openings in the throat-plate 78 and issecured upon the feedbar 74 pivotally connected at its rearward end withthe upwardly extending feedrocker 75 of the rock-shaft 76 having thelateral arm 77 pivotally connected with the lower end of the link-bar 78 forked at its upper end to embrace the block 7 9 fitted upon thefeed-actuating eccentric upon the main shaft, the link-bar beingsustained by a pivotal connection with the swinging link 80 journaledupon the fulcrum-stud 81 carried by the feed-regulating bellcrank-lcver82 mounted upon the fixed stud 83. The opposite end of the feed-bar hasa sliding and pivotal connection with a lateral crank-arm 84 of thefeed-lifting rock-shaft 85 having the lateral arm 86 pivotally connectedwith the lower end of the pitman 87 having at its opposite end the strap88 embracing the feed-lifting eccentric upon the main-shaft. Opposed tothe feed-dog is the usual presserfoot 89 attached to the spring-pressedresser-bar 90.

The machine is provided with the usual needle-thread tension device 91through which the thread a is led from the source of supply through theguide-eye 92, and be -neath the check-spring 93 and under thecompensator arm 94: carried by the presserbar, through the eye .71 ofthe take-up arm to the needle-eye.

In the operation of the rotary hook machine, in which the presentimprovement is shown embodied, the needle descends and as it begins torise presents a loop of needle thread a which is entered by the point'6of the loop-taker beak, the lower thread 6 lead ing) from the outer endof the thread-case to the needle-hole 73* of the throat-plate. As thehook-member l continues its loopcasting movement, one limb of the needlethread loop is thrust backwardly by the acswinging tion of the rearwarddeflecting edge of the the inclined loop-deflecting edge 8 of theloop-deflector 7 so as to cause it to lead from the extreme forward edgeof the externally cylindrical hook-shank4 over which it extends directlyto the needle-hole 73.

In completing a semi-rotation from loopseizing position, the hook-membercarries the forward limb of the thread-loop with-' out obstruction overthe outer face of the bobbin-case to cast-off positions, as representedin full lines in Fig. 1 and in dotted lines in Fig. 2 wherein thetake-up is en abled to immediately begin its rising or thread drawingmovement. The take-up is so constructed and timed relatively to themovement of the loop-taker that the reduotion in the size of thedistended thread-loop progresses in such manner that the latter is drawngradually from the beak of the hook but not wholly disengaged therefromuntil the point of the latter has traversed nearly a quartercircumference, so as to control the loop atsuch time against twisting orkinking. During this period, the threadloop remains confined between theshoulders 14 and 15 and periphery of the bobbincase holder and thehook-ring 1, the loopconfining shoulder 15 remaining housed within theraceway .10. As the take-up arm 68 approaches its highestv orstitch-setting position, the hook-member advances sufliciently touncover the loop-confining shoulder- 15 so as to release the thread-loopwhich is drawn up by the take-up and around the strand oflower-thread 1) leading from the bobbin-case to the work.

By means of the construction just described, the hook-member is causedto manipulate the needle-thread loop with .certainty, not only incasting the forward limb thereof freely over the front face of thebobbin-case without employment of an inclined cast-off surface upon theexterior of the hook-member, but in insuring the presentation of theother limb of the thread loop for engagement with and detention by theinwardinclination of thebeak 5 of the hookmember, the outer face of thelatter assumes -an upwardly inclined "position when the. throat 9reaches its lowest point as represented in dotted lines in'Fig. 2,thereby in suring an early cast-off of the thread-loop. As beforedescribedi" the beak is flanked inside and outside by thread deflectingelemenace spreads the loop toward the rear while the spreading ordeflecting element 8 deflects it to the forward corner of the triangularbeak. T he inner branch of the loop is de flected inwardly by thedeflecting surface of the nose 1-8 into the path of the bobbincarrier.shoulder la. The spreading of the loop is mainly in a rearward directionby the edge 6*; there being substantially no spreading in a radiallyoutward direction and the spreading in a radially inward direction bythe deflecting surface of the nose 18" being of comparatively small eX-tent. When the hook has advanced to the cast-off position, which is atan early point in its path, the form and position of the beak facilitatethe early cast-off because the movement of the loop from the base to thebody of the beak is slightly inward or to Ward the center and isaccompanied by the rapid lessening of the yvidth from the base to. thepoint.

"To insure the early release of the threadloop from the interlockingconnection between the hoolemember and the threadcase, the hook-ring iscut away on one side so as to reduce the length of the raceway 10 toalittle more than a semi-circumference, whereby the confining shoulder15 is caused to emerge from such raceway a considerable time before thehook-member completes its loop-casting rotation. In order to prevent thelateral displacement of the thread-case when the bearing between thehook-member an'd thread-case is the shortest, owing to the interruptionof the raceway 10 and the thread-case tongue, such raceway and tongueare formed of ?..-shape so that the lip 13 has a bearing in the hookringupon both faces.

It has been customary heretofore to provide a stationary thread-casewith a simple peripheral bearing rib, lying in a single plane and toprovide a cupped hook-mem-. her .with an internal annular groove facingtoward its axis to receive such bearing rib. With ,the employment ofsuch construction it was impracticable to sufiiciently reduce the lengthof the bearing between the sta tionary and movable parts to provide-ferboth the early cast-elf and release of the needle-thread loopwithoutrelative dis placement of the parts. By the present constructionthe lengths of the interrupted portions of the hook-ring and thread-casemay aggregate substantially a semi-circumference while'the aggregatelengths of bearsurface uponaopposite sides of the lip 13 exceed acomplete circumference, thus insuring an adequate bearing between thethread-case and hook-ring in all positions of the latter.

It has been customary heretofore in the construction of a loop-takerhaving a tongue-andgroove connection between the hook-ring andthread-case to form a part of the raceway for confining such members inaxial relation upon a removable section of one or the other of suchmembers. According to the present improvement, the raceway 10 is made ofsmaller diameter than the beak of the hook-member and its shank, and inthe practical construction of the hook is adapted to be formed by thesame cutting tool which cuts the axial cavity to admit the thread-case,the raceway groove being concentric with the hook-ring and facing forwardly, as represented. particularly in Figs. 4, 5 and 6. This method ofconstruction insures absolute accuracy in the position of the groove andwholly obviates the accurate fitting of one of the circular wallsthereof upon a separate section of the hook-ring or the bobbin-caseholder and consequently involves a very great saving in the cost ofmanufacture. It will be observed that the flat cover-plate 18 is of suchform as to be readily stamped out of sheet metal and to require nofitting whatever to enable it to perform its function, which is merelyto close the racewa and securely confine the bearing tongue tierein.

To secure the best results in the loop-cast ing operation, it has beenfound desirable to lead the lower thread from substantially the frontface of the bobbin-case and as dircctly possible to the work. Accordingto the present invention, a transverse tongue 4 gardless of defects inthe thread or other conditions and provides for uniformity in thedelivery of the bobhin'thread in the stitch-forming operation.
